The technical solution of the present invention will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

In order to achieve high-magnification optical zoom, the prior art generally solves the problem of miniaturization by means of multi-camera relay zoom.

Although there are ultra-high-definition lenses on the market, due to the performance of the image signal processing ISP unit, the ultra-high-definition multi-camera zoom function has not been realized on the market.

First of all, the application scene of the present invention can be a camera or other shooting equipment. In order to realize multi-camera input on the hardware, the present invention can be applied to a scene containing multiple lenses, such as a telephoto lens, a medium-focus lens and Short-focus lens, this solution can realize free switching between telephoto lens, medium-focus lens and short-focus lens, so as to realize ultra-high-definition multi-camera zoom function.

Referring to FIG. 1 , it is a schematic structural diagram of an ultra-high-definition multi-camera input switching device provided by an embodiment of the present invention. The ultra-high-definition multi-camera input switching device includes an image signal processing ISP unit. It can be understood that the ISP unit can be a The image processor ISP can process image signals at high speed.

In order to realize the ultra-high-definition multi-camera zoom function, this solution is provided with a switch unit, and the short-focus lens and the medium-focus lens are electrically connected to the corresponding data interface of the ISP unit through the switch unit. The telephoto lens is electrically connected to the corresponding data interface of the ISP unit.

It can be understood that in this solution, according to the actual shooting parameters, the switch unit can be used to realize the input switching between the short-focus lens, the medium-focus lens and the long-focus lens.

In practical applications, since the user will adjust the parameter settings of the camera during shooting, such as adjusting the focal rate value, this solution can set the state of the switch unit according to the state of the focal rate value to realize short-focus lens, medium-focus lens and telephoto lens Input switching between lenses.

In some embodiments, in order to realize the above input switching, the switch unit includes a first switch and a second switch, and the first switch and the second switch are electrically connected; wherein, the short-focus lens passes through the first The switch and the mid-focus lens are respectively electrically connected to corresponding data interfaces of the ISP unit through the second switch.

It should be noted that the first switch and the second switch are electrically connected, and in a certain state, the first switch and the second switch can realize communication. Wherein, both the first switch and the second switch are SWITCH switches. The SWITCH switch is a toggle switch, and the first switch and the second switch are combined into a switch unit to realize switching of input signals.

In practical applications, the ISP unit includes multiple data interfaces, such as a first interface, a second interface and a third interface. Wherein, in some embodiments, the first interface is, for example, the MIPI0 interface, the second interface is, for example, the MIPI1 interface, and the third interface is, for example, the MIPI2 interface; in other embodiments, the data interface can also be SLVS-ES /LVDS/DC-CAMERA/BT1120/BT656 and other input interfaces.

In some embodiments, the short-focus lens may be electrically connected to the first interface of the ISP unit through the first switch, and the medium-focus lens may be electrically connected to the second interface of the ISP unit through the second switch, so The telephoto lens is electrically connected to the third interface of the ISP unit. For example, referring to FIG. 2 , when the anxiety value of the input signal is in the short-focus range, the switch unit is in the state of connecting the short-focus lens to the data interface of the ISP unit, that is, to realize the connection of the short-focus lens.

Specifically, the state of the first switch may be that one end is connected to the short-focus lens, and the other end is connected to the first interface, so as to connect the short-focus lens and the first interface to realize the access of the short-focus lens signal.

Another example, referring to FIG. 3 , when the anxiety value of the input signal is in the mid-focus range, the switch unit is in the state of connecting the mid-focus lens to the data interface of the ISP unit, and the short-focus lens is in the off state. That is, when the user adjusts the anxiety value from the short-focus range to the medium-focus range, it is necessary to switch to the input signal of the medium-focus lens and cut off the input of the short-focus lens. At this time, the switching unit can be used to realize the switch.

Specifically, the state of the second switch can be that one end is connected to the medium-focus lens, and the other end is connected to the end of the first switch close to the short-focus lens. At this time, the first switch and the second switch are connected to each other, and the state of the first switch can be Connect the first interface to connect the medium-focus lens and the first interface to realize the access of the medium-focus lens signal. At the same time, because the first switch disconnects the connection with the short-focus lens, it cannot receive the signal at this time. The input signal of the short-focus lens, that is, the cut-off of the short-focus lens is performed.

Another example, referring to Fig. 4, when the anxiety value of the input signal is in the telephoto range, the switch unit is in the state of connecting the telephoto lens to the data interface of the ISP unit, and the short-focus lens and the The mid-focus lens is disconnected, that is, when the user adjusts the anxiety value from the mid-focus range to the telephoto range, it needs to switch to the telephoto lens input signal and cut off the input of the medium-focus lens and short-focus lens.

Specifically, at this time, it is only necessary to connect the telephoto lens to the third interface of the ISP unit, cut off the input of the medium-focus lens and the short-focus lens, and only have the input of the telephoto lens at this time. Wherein, the disconnection mode may be, for example, not to activate the first interface and the second interface, but to activate only the third interface.

In practical applications, the above switching can be applied in the 8K resolution mode, because due to the performance limitation of the image signal processing ISP unit, only one signal is input in the 8K resolution mode, for example, the above short-focus lens and medium-focus lens You can switch between the telephoto lens and the ultra-high-definition multi-camera zoom function.

It should be noted that the application of this embodiment is not limited to the above-mentioned 8K resolution mode, and may also be scenes with larger resolutions such as 5K resolution, 5.2K resolution, 5.7K resolution, and 6K resolution. No longer.

In practical applications, if it is in the mode of 4K resolution, the performance of the ISP unit can meet the processing requirements. See Figure 5. The switch unit can be used to connect the short-focus lens and the medium-focus lens to the data interface of the ISP unit, and the The telephoto lens is connected to the data interface of the ISP unit to realize the simultaneous access of three 4K signals, and at the same time the first interface, the second interface and the third interface are also activated to receive input signals. In addition, it can also support 3-channel simultaneous recording and preview, and also supports single-channel 4K fusion and smooth optical zoom.

Referring to FIG. 6 , it is a schematic flowchart of an ultra-high-definition multi-camera input switching method provided by an embodiment of the present invention. The execution body of the method shown in FIG. 6 may be a software and/or hardware device. The execution subject of this application may include but not limited to at least one of the following: user equipment, network equipment, etc. Wherein, the user equipment may include but not limited to a computer, a smart phone, a personal digital assistant (Personal Digital Assistant, PDA for short), and the electronic equipment mentioned above. Network devices may include, but are not limited to, a single web server, a server group composed of multiple web servers, or a cloud composed of a large number of computers or web servers based on cloud computing, where cloud computing is a type of distributed computing consisting of a group of loosely coupled A super virtual computer composed of computers. This embodiment does not limit this. Including step S101 to step S102, specifically as follows:

S101. Identify a focal rate value of an input signal.

It can be understood that the solution may first receive an input signal of a lens, such as an input signal of a short-focus lens, a medium-focus lens, or a telephoto lens, and then identify the focal power value of the input signal. Wherein, the focal ratio value may be changed according to the user's operation of switching the zoom through the APP on the electronic device.

S102, if the focal rate value is in the short-focus range, connect the short-focus lens to the data interface of the ISP unit according to the switch unit;

It should be noted that this solution can automatically complete the switching of the input signal through the recognized focal rate value, so as to realize the ultra-high-definition multi-camera zoom function.

For example, referring to FIG. 1 , if the focal rate value is in the short-focus range, the switch unit may be triggered to connect the short-focus lens to the data interface of the ISP unit, that is, to realize the connection of the short-focus lens.

Specifically, this solution can automatically switch the state of the first switch, so that one end of the first switch is connected to the short-focus lens, and the other end is connected to the first interface, so as to connect the short-focus lens and the first interface to realize the short-focus lens signal access.

Another example, when the focus rate value enters the medium focus range from the short focus range, the medium focus lens is connected to the data interface of the ISP unit according to the switch unit, and the short focus lens is disconnected, that is, when the user will be anxious When the value is adjusted from the short-focus range to the medium-focus range, it is necessary to switch to the input signal of the medium-focus lens and cut off the input of the short-focus lens. At this time, the switch unit can be used to switch.

Specifically, this solution can automatically switch the state of the first switch and the second switch, so that one end of the second switch is connected to the medium-focus lens, and the other end is connected to the end of the first switch close to the short-focus lens. The state of the first switch can be connected The first interface is used to connect the medium-focus lens and the first interface to realize the access of the medium-focus lens signal. At the same time, because the first switch disconnects the connection with the short-focus lens, the short-focus lens cannot be received at this time. The input signal of the focal lens, that is, the cut-off of the short focal lens is performed.

In practical applications, after the medium-focus lens is connected to the data interface of the ISP unit according to the switch unit, and the short-focus lens is disconnected, the short-focus lens and the short-focus lens can also be adjusted based on the preset zoom model. The medium-focus lens performs smooth zoom processing, which will achieve a smooth zoom effect during the switching process between the two lenses.

In yet another example, when the focal rate value enters the telephoto range from the middle focus range, the telephoto lens is connected to the data interface of the ISP unit, and the middle focus lens is disconnected, that is, when the user changes the anxiety value from the middle focus When the focal range is adjusted to the telephoto range, it is necessary to switch to the input signal of the telephoto lens and cut off the input of the medium focal length lens and the short focal length lens.

Specifically, this solution only needs to automatically connect the telephoto lens to the third interface of the ISP unit at this time, and automatically cut off the input of the medium-focus lens and the short-focus lens, and only the input of the telephoto lens is available at this time. Wherein, the disconnection mode may be, for example, not to activate the first interface and the second interface, but to activate only the third interface.

Referring to FIG. 7 , it is a schematic flowchart of another ultra-high-definition multi-camera input switching method provided by an embodiment of the present invention, including steps S201 to S202, specifically as follows: including:

S201, connecting the telephoto lens to the data interface of the ISP unit, and connecting the short-focus lens and the medium-focus lens to the data interface of the ISP unit according to the switch unit;

S202. Perform fusion zoom processing on the short-focus lens, the medium-focus lens, and the telephoto lens.

It is understandable that if it is in 4K resolution mode, the performance of the ISP unit can meet the processing requirements, so the switch unit can be used to automatically connect the short-focus lens and the medium-focus lens to the data interface of the ISP unit, and the telephoto lens can be connected to the data interface of the ISP unit. The lens is connected to the data interface of the ISP unit to realize the simultaneous access of 3 channels of 4K signals. At the same time, the first interface, the second interface and the third interface are also activated to receive input signals. In addition, it can also support 3-channel simultaneous recording and preview, and also supports single-channel 4K fusion and smooth optical zoom.

It should be noted that this embodiment is not limited to the application in the above-mentioned 4K resolution mode, and this embodiment can be applied to some application scenarios with a smaller resolution, so details will not be repeated here.
